MILK-CAN PERFORATOR AND PROTECTOR.

Application filed May 20, 1922. Serial No. 562,384.

To all whom it may concern.

Be it known that I, JOHN BUSSANICH, a citizen of the United States, and a resident of Dockton, Vashon Island, county of King, and State of \Vashington, have invented certain new and useful Improvements in.Milk- Can Perforators and Protectors, of which the following is a specification.

This invention relates to improvements in milk can perforators and protectors, and more particularl to devices of that character that are app icable to cans wherein condensed milk is sold.

The object of my invention is to provide a device of the above character which may be easily and quickly applied and secured to the can, and which comprises means whereby the can may be perforated so as to provide an air inlet and a pouring outlet, and which embodies means whereby the openings may be protected at all times and at the same time kept open and clean.

Other objects of the invention reside in the details of construction of the parts'embodied in the device, and in their combination and mode of operation.

In accomplishing these and other objects of the invention, I have provided the improved details of construction, the preferred forms of which areillustrated in the accompanying drawings, wherein- Figure 1 is a perspective view of a can perforating and protecting device embodied by the present invention, as applied to a can.

Figure 2 is a top view of the same.

Figure 3 is a front view of the device, showing the perforating armsv in raised position to uncover the can openings.

Figure 4 is a horizontal, sectional view through the device, showing the construction and mounting of the perforating arms.

Figure 5 is a side view 0 the device.

Referring more in detail to the several views of the drawings- 1 designates what may be an ordinary type of can wherein condensed milk, or the like, may be contained and over the upper end wall 2 of which a perforating and protecting device. embodied by the present invention, is applied. This device comprises a base, or clamping plate 3 provided at one end with spaced hooks 4 and 5 and engaging one side edge of the can, andat its other end has a hook 6 for engaging the opposite side edge. Centrally of the plate is an upwardly extended loop 7 whereby a desired resiliency is provided which permits the hooks to be drawn tightly against the can walls to hold the plate tightly in functional position. The means whereby this tighteningaction is effected comprises a pin 9, see Figure 5, that is extended across the lower portion of the loop and which has a head 10 at one end and a block 11 at its opposite end to which is pivotally fixed a lever 12 having an eccentrically formed head 13 which operates against that side of the loop, when the lever is pressed downwardly from position as shown in Figure 4 to position shown in F igure 1, to draw the loop together and thereby tighten the hooks against the can.

Pivotally mounted at their inner ends on the pin 9, between the vertical portions of the loop 7, are oppositely extending arms 15 and 16. each of which at its outer end carries a cam perforating pin '17. Mounted on the upper ends of these pins are pads 18 against which pressure may be applied to press the pointed lower ends of the pins through the can end. Also mounted about the lower portions of the pins, are inverted, cup shaped pads 19 whereby the openings formed in the can end are protected against the collection of dirt thereabout, and from insects, and are sealed against possible leakage.

It is preferred that the arms 15 and 16 be made by bending strips of metal at the centers about the pins 17, as shown in Figure 5, and extending rivets 22 therethrough next to the pins, then spreading the end portions of the arms apart so as to add strength and rigidity to the construction.

In order that these arms 15 and 16 may be easily raised with the same hand in which the can is held while its contents is being poured out, I have provided a lever 25 having a portion 26 depending along the side wall of the can. as shown in Figures 1 and 4, and having a horizontal arm 27 extended to a point directly above the loop 7. This lever is mounted pivotally upon a standard 28 formed at one end of the plate 3 between the hooked portions 4 and 5.

Pivotally fixed to the end of the lever arm 27 are two links 28 and 29 which, at their lower ends. are pivotally connected respectively to the perforating arms 15 and 16 so that, when the lever handle 26 is pressed against the can wall, the arms 15 and 16 Wlll grasped so that the lever arm 26 may Pressure is then applied be raised and the perforations formed by the pressingof the pins 17 through the can end, will be uncovered.

A coiled spring 30 is fixed at its opposite ends to the lever arm 27 and to the plate 3 to yieldingly retain the perforating arms in lowered position and the pads 19 tightly against the can.

In order that the clamp plate will release itself from the can when the clamping lever 12 is thrown upwardly, I have placed a coiled compression spring 35 between the sides of the loop 7 and about the pin 9 which acts to spread the loop and extend the length of the plate between its hooked ends.

Assuming that the device is so constructed, to use the same it is placed over the end of a can and then the lever 12 pressed downwardly-to draw the loop 7 together and tighten the hooks at opposite ends of the plate against thecan edges. against the pads 18 whereby the lowerpoint-ed ends of the pins 17 will be pressed through the can end wall at diametrically opposite points thereof. The tension of the spring 30, pulling downwardly on the lever 27, through the connecting links 28 and 29, retains the arms 15 and 16 tightly against the can so that the pins normally retain the perforations closed, and the pads 19 cover the can about the perforations.

To pour milk from the can, the can is be pressed against the can side wall, and this will lift the lever arm 27 and arms 15 and 16 to cause the perforations to be uncovered. The milk can then be poured from one opening while air is admitted into the can through the other.

When the lever 26 is released, the spring 30 moves the parts back to normal position.

To remove the device from the can, the lever 12 is moved upwardly so that its eccentric head 13 is disengaged from the side portion-of loop 7 and spring 35 causes the the hooks at the ends of the plate released from the can.

Having thus described my invention,

what I claim as new therein and desire to secure by Letters-Patent, is:
